APPARATUS FOR ROLLING CURVED SECTIONS
Abstract of the Disclosure
A metal sheet is formed into an arcuate contour by
rolling the sheet under high pressure on an elastomeric
pad (24) supported by a rigid frame. A pair of laterally
spaced rollers (30, 32) are used to form the arc. Each moves
from the transverse edge of the sheet inwardly and crosses
the center line of the sheet. Under the high pressure
applied to the rolls the sheet yields to form the arc and
the elastomeric material elastically deforms as the arc is
formed. The rollers depend from vertical guides (34, 36)
which follow a track extending transversely across the sheet.
A guide track (38) is provided in a transverse beam located
above the rolls and the guides. Hydraulic or pneumatic
jacks (70) apply pressure to the beam which in turn applies
pressure to the rolls.
